For those who don't know what Stone Monster eggs are, let me explain, last season, you could buy spawn eggs for a bunch of mobs. This season, they were glitched in shops and became Stone Monster eggs, an item with the pink and black missing texture that spawns a stone block that turns into a silverfish if you hit it. These were removed a few weeks ago, and I feel that a few months further in, they could become quite valuable. I have 30 in my pv 1, so heres hoping I can sell some later (wish I had stocked up before the removal.)
